Recently added: HART communication with the IQ SENSOR NET

Recently added: HART communication with the IQ SENSOR NET

With the DIQ/S 281-HART monitor variant, you can now rely on the HART Communication Protocol (Highway Addressable Remote Transducer) without having to miss out on the advantages of the IQ Sensor Net.

The DIQ/S 281 Universal Monitor

... is the heart of the digital and cost-effective single parameter measuring point with proven IQ Sensor Net technology and IQ sensors for the standard parameters.

Its new variant DIQ/S 281-HART

With the new variant, we have added a component with HART interface to our comprehensive IQ Sensor Net measuring system. The DIQ/S 281-HART universal monitor is used in projects where data transmission via HART protocol is required. The DIQ/S 281-HART can be easily integrated into existing systems. In addition, the monitor offers a menu structure that is identical throughout IQ Sensor Net so that the start-up and operation is consistent with other monitors. This simplifies everyday work and avoids having to learn different systems.

All advantages at a glance

  • Standardized HART communication
  • 2 relays for alarms of main and secondary measured value
  • Proven and reliable IQ Sensor Net technology
  • Free software updates with new functions

    Application areas

    Use the DIQ/S 281-HART to monitor the standard parameters D.O., pH/ORP and conductivity as well as turbidity, solids or sludge level in the fields of wastewater, drinking water and industry.
